Phenolic Ring Tweeter Replacement for AR-4X CTS Marantz and More 8 Ohm is rated 4.8537 out of 5 by 41.
Rated 5 out of 5 by from BOLT FOR BOLT DROP IINTHESE WERE REPLACEMENTS FOR THE TWEETERS IN A PAIR OF 50 YR OLD AR-4AS. THEY WERE BOLT FOR BOLT REPLACEMENTS AND TOOK ABOUT AN HOUR TO REPLACE BOTH, INCLUDING GRILL REMOVAL. AFTER A YEAR AND A HALF OF LISTENING THEY SOUND GREAT.THEY ALSO APPEAR TO BE A REPLACEMENT FOR THE TWEETERS IN A PAIR OF ALTEC SANTANAS.

Rated 4 out of 5 by from Very good, maybe a touch "shouty"I bought a pair of these for a custom build. I used a home made 2.5k 1st order butterworth crossover and an old set of 8" woofers. They sound very good. I do "feel" they have a little bit of a spike at around 3-5k hz. This could be my xover though. I am going to add a series notch filter and maybe an l-pad too. Overall I am quite pleased with them. Considering the price, I think they are an excellent value.

Rated 5 out of 5 by from Sounds like the original!I bought these to replace a blown tweeter in an old pair of KLH Model 17s. Sounds just like the original tweeter. They are not a direct replacement because the mounting diameter is smaller. They will fall through the cutout in the speaker. Being my tweeter was blown, I pryed apart the tweeter and used a whizzer wheel to cut off the mounting flange from the magnet structure of the old tweeter. $ sheet metal screws to mount the flange to the new tweeter and in it went. Don't forget to silicone over the mounting rivet for the speaker terminals if used in an acoustic suspension design like the KLHs. otherwise you"ll have a small port!!

Rated 5 out of 5 by from Direct replacement for Altec Lansing 887a "Capri"Recently picked up some Altec Lansing 887a "Capri" speakers on Craigslist. Came with a Pioneer stereo, only the tweeters didn't work. Ordered these as replacements and they were a direct fit.One note--one of the tweeters was DOA, but PE immediately replaced it, and told me to keep the DOA one.Once installed, I couldn't believe how great these mini bookshelf speakers sounded. I'm very impressed.

Rated 5 out of 5 by from Sound Is excellentI got a pair of these for a pair of JBL L88. They sound excellent, and imaging is great. The metal flange around the outside is slightly thinner than I would have liked, but overall the build quality is great.

Considering these for a classic 1978 Allison Four speaker system. I already have the Goldwood GW-8PC/4 woofs as replacements and new 2 Khz 2-way x-overs. Two of the four tweets are strong but the other two are a tad weak. Ur thoughts please.

I was looking at using this tweeter for a replacement in my KLH model 17 speakers. I've read that it's a suitable replacement but that it's not a drop in and will require an adaptor plate to fit perfectly.  Suggestions would be appreciated. Thx !

Hello, I have a pair of Marantz HLM 312 speakers, these look to be compatible but upon inspecting the existing tweeter they are marked as 4 ohm tweeters. Would these, being 8 ohm, work in my speakers?

I want to install these into a pair of AR6 speakers. The cutout is 62mm or 2 1/2" and the rebated OD slot is 93mm or 3 " and 10/16 . Will these fit?

Asked by: Marko99
This tweeter has an overall faceplate diameter of 4-1/4" and requires a cutout diameter of about 3-3/16". It sounds like the enclosure will require some modifications in order to fit properly.
